The theft of a laptop computer containing the personal details of hundreds of staff at Cornwall's Eden Project is being investigated.
The computer contains the names, addresses, bank details, National Insurance numbers and pay rates of 500 employees at the attraction.
It was stolen from a car of an employee who works for Moorepay Ltd, who handle the attraction's payroll.
The company, which is based in Hampshire, was unavailable for comment.
Tim Smit, Eden's creator, said: ''A computer containing the personal details of employees of a number of companies, including the Eden Project Ltd, has been stolen from the car of an employee working for a contracted payroll company.
''Suffice to say we are appalled at the lapse of security and are making sure that our personal data is never put in such a vulnerable position again.''
Police investigating the 1 June theft are monitoring bank accounts of employees.
